The main thesis is in the title, but I will explain. At the beginning of the game, it is difficult to get randomness for unnecessary leader traits. But once you get +1 to the starting level of leaders, hiring turns into a damned casino. That is why I am looking for a mod that will allow me to pump leaders like the Luminary in the origin "Under the One Authority". That is, I will hire a level 2 leader with one trait, and then choose the second, and not hire Frankenstein with two opposite traits.
